Amorphous shaped charge component and manufacture

ABSTRACT

A shaped charge incorporating an amorphous-based material component. The amorphous-based material component may be a liner for the shaped charge to enhance a jet for a perforating application. Other components of the shaped charge and/or perforating gun that accommodates the shaped charge may be of amorphous-based materials. Further, the liner and other components of the shaped charge may be manufactured by way of three dimensional printing. Indeed, a multi-material three dimensional print application may be utilized to form shaped charge components simultaneously along with an entire perforating gun system. Thus, tailored morphology and material gradient characteristics may be readily incorporated into the gun and shaped charge components with a considerable degree of precision.

BACKGROUND

Exploring, drilling and completing hydrocarbon and other wells aregenerally complicated, time consuming and ultimately very expensiveendeavors. As a result, over the years well architecture has become moresophisticated where appropriate in order to help enhance access tounderground hydrocarbon reserves. For example, as opposed to wells oflimited depth, it is not uncommon to find hydrocarbon wells exceeding30,000 feet in depth. Furthermore, as opposed to remaining entirelyvertical, today's hydrocarbon wells often include deviated or horizontalsections aimed at targeting particular underground reserves.

While such well depths and architecture may increase the likelihood ofaccessing underground hydrocarbon reservoirs, other challenges arepresented in terms of well management and the maximization ofhydrocarbon recovery from such wells. For example, during the life of awell, a variety of well access applications may be performed within thewell with a host of different tools or measurement devices. However,providing downhole access to wells of such challenging architecture mayrequire more than simply dropping a wireline into the well with theapplicable tool located at the end thereof. Indeed, a variety ofisolating, perforating and stimulating applications may be employed inconjunction with completions operations.

In the case of perforating, different zones of the well may be outfittedwith packers and other hardware, in part for sake of zonal isolation.Thus, wireline or other conveyance may be directed to a given zone and aperforating gun employed to create perforation tunnels through the wellcasing. Specifically, shaped charges housed within the steel gun may bedetonated to form perforations or tunnels into the surroundingformation, ultimately enhancing recovery therefrom.

The profile, depth and other characteristics of the perforations aredependent upon a variety of factors in addition to the materialstructure through which each perforation penetrates. That is, the jetformed by the detonation of a given shaped charge may pierce steelcasing, cement and a variety of different types of rock that make up thesurrounding formation. However, characteristics of different componentsof the shaped charge itself may determine the characteristics of the jetand ultimately the depth, profile and overall effectiveness of eachgiven perforation as described below.

Among other components, a shaped charge generally includes a case,explosive pellet material and a liner. Thus, detonation of the explosivewithin the case may be utilized to direct the liner away from the gunand toward the well wall as a means by which to form the noted jet.Therefore, understandably, the characteristics of the jet are largelydependent upon the behavior of the liner and other shaped chargecomponents upon detonation. For example, a solid copper or zinc linermay be utilized to generate a jet of considerable stretch with a head ortip that travels at 5-10 times the rate of speed as compared to thespeed at the tail. Depending on the casing thickness, formation type andother such well-dependent characteristics, this type of liner isgenerally of notable effectiveness in terms of achieving substantialdepth of penetration.

Unfortunately, a solid metal liner of the general type described abovefaces limitations in terms of the actual effectiveness of thepenetration. For example, as described above, the perforation is atunnel into the formation from which hydrocarbons may be extracted.However, a solid metal liner is prone to penetrate the formation in amanner that often leaves a slug of material lodged within theperforation. Thus, even where the perforation is of notable depth, it isoften largely obstructed. Further, as the solid liner material begins tostretch and break up, it begins to tumble resulting in a loss ofcoherence and penetrating character.

In order to avoid such issues with solid liners, a crystalline powderliner may instead be utilized. For example, a crystalline base materialmay be mixed with a binding agent such as copper or lead and pressedinto a liner component for assembly into a shaped charge. Thus, upondetonation of the shaped charge, a perforating jet will emerge from acrystalline powder material that readily disintegrates as opposed toemerging from a solid liner that is prone to leave behind a slug withinthe perforation.

Unfortunately, while the crystalline powder liner is not as prone toleave behind an occlusive slug, it is also not as prone to develop a jetof notable stretch or effectiveness in terms of perforating depth. Thatis, given the near immediate disintegration of the liner, its stretch,density distribution and other factors that might enhance depth arelimited. Ultimately, this leaves the perforating gun operator with theundesirable choice between utilizing a shaped charge that may result ina perforation that is compromised by a slug versus one that may resultin a perforation that is limited in terms of penetration depth.

SUMMARY

A shaped charge is disclosed for use in perforating a tunnel into aformation at a well wall with a jet. The shaped charge includes a casewith an explosive material therein. A liner is provided as part of theshaped charge and is of an amorphous-based material to enhance a stretchof the jet and to substantially avoid obstruction of the tunnel thereby.The explosive material and/or the case may also be made up of such anamorphous-based material. Additionally, each of the case, explosivematerial and liner components of the charge may be formed as part of thesame three dimensional print manufacturing application.

DETAILED DESCRIPTION

Embodiments are described with reference to certain downhole perforatingapplications in vertical cased well environments. In particular,wireline deployed applications utilizing a shaped charge assembly systemare detailed. However, other forms of deployment and well architecturesmay take advantage of the shaped charge assembly system as detailedherein. For example, multi-zonal wells may benefit from such a systemduring stimulation operations. Regardless, so long as shaped chargecomponents take advantage of amorphous materials, such as an amorphousliner, significant benefit may be realized in the perforatingapplication.

Referring now to FIG. 1, a side cross sectional view of an embodiment ofa shaped charge 100 is shown. The charge 100 utilizes a liner 101, atleast a portion of which is primarily and/or exclusively of an amorphousmaterial. That is, the entire liner 101 may be of such a material orhave a segment or portion that is of such a material. Regardless, theamorphous material portion may be referred to herein as an“amorphous-based” material. For example, as described in further detailbelow, the entire liner 101, or a predetermined portion thereof, may beof a silicon, metallic or other suitable glass with a variety ofdifferent fillers or additives incorporated therein. Regardless, as alsodetailed further below, a liner 101 of such an amorphous-based materialmay be utilized to enhance the stretch of a jet 400 during perforatingin a well 380 such that substantial depth of a perforation 425 may beattained (see also FIGS. 3 and 4A). Further, the amorphous nature of theliner 101 may substantially remove the possibility of liner materialforming a slug that might undesirably block an end 427 of theperforation 425 (see FIG. 4A).

Continuing with reference to FIG. 1, in addition to the noted liner 101,the shaped charge 100 includes a case 150 that accommodates an explosivepellet material 175. The explosive pellet 175 is located between theliner 101 and the case 150 with the case 150 being made up of a robustmaterial such as steel or zinc. Thus, once a fuse 110 is triggered toignite the pellet 175, the material of the liner 101 may breach the voidspace 125 of the charge 100 and extend beyond a seal 155 of the case 150to form a jet (e.g. 400 of FIG. 4A). In theory, the longer the jet 400or the greater the stretch (S), the deeper the penetration orperforation 425 (again see FIG. 4A). As detailed further below, suchcharacteristics may be achieved through use of a liner 101 that is of anamorphous-based material.

The case 150 may be formed by conventional machining such as computer,numeric code or forging. The amorphous-based material liner 101 may alsobe separately machined from a solid bar. Additionally, the liner 101 maybe formed by stamping, pressing or other suitable techniques.Regardless, the separately formed case 150 and liner 101 may beassembled together with the pellet 175 sandwiched therebetween and thecase seal 155 placed thereover. However, in an embodiment detailedfurther below with reference to FIG. 5, any one of the case 150, pellet175 or liner 101 components may be formed via emerging three dimensionalprint techniques. Indeed, all three components may be simultaneouslyformed as part of the same three dimensional printing application. Oncemore, in addition to the use of an amorphous-based material for theliner 101, an amorphous-based material may also be utilized in formingthe case 150. In this embodiment, the comparatively higher density andimpedance available from such a material structure may be takenadvantage of to focus explosive energy into the forming jet duringcharge detonation as described further below.

Referring now to FIGS. 2A, an enlarged view of the amorphous materialliner 101 and surrounding architecture taken from 2-2 of FIG. 1 areshown. The representative view of the amorphous liner 101 of FIG. 2A isshown in contrast to the conventional prior art crystalline powder liner200 and surrounding structure of FIG. 2B. For example, the prior artcrystalline liner 200 of FIG. 2B is of a repeating uniformity as apowder that is represented as a multitude of spheres in a pressed linerform. Thus, upon triggering of the underlying pellet 175, the nearimmediate dispersal of powder from the pressed liner form may beunderstood. While adept at avoiding the formation of a slug and otherlarge debris issues, the near immediate dispersal may adversely affectthe ability of the emerging jet to display significant stretch.

With particular focus on FIG. 2A, the structure of the amorphous-basedliner 101 may avoid the near immediate disintegration and dispersal ofthe prior art liner 200 of FIG. 2B. In this respect, the amorphous-basedliner 101 may be more like a conventional solid liner. Yet, unlike asolid liner, the amorphous-based material is not a monolithic solid, butrather, is comprised of a suitable glass-like structure as depicted.Thus, with added reference to FIG. 4A, a notable stretch (S) may beachieved in jet formation, while at the same time, the liner materialremains prone to substantial breakup. As a result, the formation oflarger slug and debris pieces may be avoided so as to prevent blockingof perforations 425 created by the triggering of the pellet 175.

Continuing with reference to FIG. 2A, with added reference to FIG. 4A,the amorphous-based liner 101 may utilize traditional liner materialssuch as tungsten, copper, lead, other metals, oxides and mixturesthereof, but in a glass form as opposed to a solid or powder form.Additionally, additives and fillers may be incorporated into theamorphous-based material. For example, binders or higher densityadditives, perhaps in crystalline powder form, may be incorporated tohelp tailor or further extend the stretch (S) of the jet 400 for sake ofachieving a deeper perforation 425. Indeed, a liner 101 of suitably highdensity amorphous material such as a tungsten glass may be of a lessvariable porosity and density as compared to a conventional crystallinepowder liner (e.g. 200 of FIG. 2B). Thus, a more continuous, cohesivelystretching jet 400 may be realized for sake of the indicated deeperperforation 425 in absence of any notable formation of blocking debris.

The amorphous-based material liner 101 of FIG. 2A may be formed in avariety of manners. For example, glass particles, including anyadditives or fillers, may be pressed like a more conventional powderliner. Similarly, such a matrix in the form of a glass bar may bemachined into a liner akin to machining of a conventional solid metalliner. However, the amorphous-based material also lends itself tocasting, injection molding and other manufacturing techniques. Indeed,as described further below, the liner 101 may even be threedimensionally printed.

Referring now to FIG. 3, an overview of an oilfield 300 is shown with awell 380 having a gun 305 located therein. The gun 305 is a perforatinggun that is loaded with shaped charges 100 such as the one depicted inFIG. 1. Specifically, the gun 305 is outfitted with ports 301 that arealigned with shaped charges that have been loaded into the gun 305.Thus, perforating of the adjacent casing 385 and formation 395 may takeplace.

The gun 305 of FIG. 3 may be manufactured through conventional machiningwith thread and seal bores at either end. A separate laser cut steeltube may directly accommodate the shaped charges with the tube loadedinto the gun 305 as a manner by which all of the charges may besimultaneously loaded.

Continuing with reference to FIG. 3, the gun 305 is deployed into thewell 380 via wireline 310 and traversing various formation layers 390,395 before reaching the target location shown. In the depictedembodiment, the gun 305 is deployed by the wireline 310 that is unwoundfrom a reel 340 at a wireline truck 375. Thus, a rig 350 may supportlowering of the gun 305 past a wellhead 360 and into the well 380 forthe noted perforating application. A control unit 377 located at thetruck 375 may be utilized for directing the gun 305 to the targetlocation in this manner. Once the perforating application is complete,the wireline 310, gun 305 and any other associated tools may be removedfrom the well 380 to enhance flow from the formed perforations 425 andwell 380 (see FIG. 4A). Of course, a variety of other modes of deliveryand retrieval may be utilized.

In order to keep the amount of debris formed during perforating at aminimum, the gun 305 may be constructed of an amorphous-based materialwith reactive agents incorporated therein. Thus, the gun 305 may beconfigured to disintegrate upon perforating with follow-on exothermal,oxidation or other tailored reaction taking place to break up theresultant debris into non-occlusive particle sizes. In fact, in oneembodiment, such a disintegrating gun is formed via a three dimensionalprint application as described further below.

Referring now to FIGS. 4A-4C, with added reference to FIG. 3, sidecross-sectional views of a shaped charge 100, such as that of FIG. 1,are shown revealing jet formation upon firing. The charges 100 may havea case 150 of steel, zinc or even amorphous material with a liner mostlikely of amorphous material. Specifically, FIG. 4A depicts the shapedcharge 100 of FIG. 1 utilizing an amorphous material liner 101 to form adeep penetrating jet 400 directed at the wall of the well 380.Alternatively, the charge 100 may utilize a liner 410 of a largerprofile to form a wide jet 401 as shown in FIG. 4B. Indeed, the liner415, jet 405 and resultant perforation 475 may all be of a tailoredmorphology as shown in FIG. 4C.

Regardless, the performance of each jet 400, 401, 405 may be enhanced bythe inclusion of amorphous material within the shaped charge 100,particularly the liner 101, 410, 415, as described above. Thus, aslug-free terminal end 427, 457, 477 of a perforation 425, 450, 475 maybe formed with sufficient penetration through casing 385, underlyingcement 490 and into the formation 395 adjacent the well 380. In oneembodiment, the liner 101, 410 and/or 415 may include reactive materialssuch as titanium to promote a reaction. Thus, the environment of thewell and/or perforations 425, 450, 475 may remain effectivelydebris-free. In fact, in one embodiment, the amorphous materials mayinclude reactive agents to allow for a lower initiation pressure duringfollow-on fracturing applications. In such embodiments, the reactivematerial may remain protected by amorphous or other surroundingmaterials but become exposed for reactivity following detonation. Suchreactivity may even be utilized to actively reduce or “clean-out” somelevel of debris within perforations 425, 450, 475.

High density powders such as tungsten may also be incorporated into theliner 101, 410, 415 to enhance jet density. Additionally, the materialof the case 150 may be tailored to match that of the liner 101, 410,415.

With specific reference to FIG. 4A, upon firing of the shaped charge100, the liner 101 exits the seal 155 and a jet 400 takes shape which isdirected at the well wall. The amorphous material of the jet 400 is of agiven stretch (S) as measured from head 405 to tail 403. The stretch (S)of the jet 400 may be enhanced by the use of the amorphous material ofthe liner 101 to provide a deeper penetration to the perforation 425.This enhanced stretch (S) may be commensurate with a significantvelocity gradient from head 405 to tail 403. For example, material atthe head 405 of the jet 400 may travel at 5 to 10 times the rate ofspeed as compared to material at the tail 403. More specifically, in oneembodiment, material at the head 405 of the jet 400 may travel at over 7km/sec. whereas material at the tail 403 travels at less than about 1km/sec.

With specific reference to FIG. 4B, amorphous material of the liner 410may also be utilized to form a wide jet 401. The jet 401 may again be ofnotable stretch (S′) from head 415 to tail 413 with a commensuratevelocity gradient as indicated above. Yet at the same time, the higherprofile liner 410 of amorphous material may be utilized in a manner thatallows for construction of a big hole charge for a wider perforation450. However, as noted above, in contrast to solid liner based charges,use of an amorphous material in construction of the liner 410 is lessprone to leaving behind a slug at the terminal end 457 of theperforation 450 that might interfere with hydrocarbon uptake.

Referring now to FIG. 4C a side cross-sectional view of anotherembodiment of a shaped charge is shown in which the liner 415 is of auniquely tailored morphology. Thus, the resultant jet 405 and ultimatelythe corresponding perforation 475 may also be of a tailored morphology.Again, a substantial velocity gradient may be present between materialat the head 419 and that at the tail 417 of the jet 405 along with asignificant stretch (S″). Thus, sufficient penetration may be attained.Further, as detailed below, the component that is this particular liner415 may benefit from manufacture by way of three dimensional printing.That is, due to small, tight specifications on component of such uniquemorphology may be more efficiently produced by way of printingtechniques. Indeed, as detailed regarding FIG. 5 below, all chargecomponents or even an entire gun system may be constructed from suchprinting techniques.

Referring now to FIG. 5, a side cross-sectional view of the shapedcharge of FIG. 4C is shown as it is being formed. Specifically, amulti-material three dimensional print manufacturing application 500 isbeing utilized to form the charge. However, in other embodimentsindividual single material components 150, 175, 415 may be formed one byone. Regardless, as noted above, three dimensional printing may beparticularly beneficial where tight specifications on small features areinvolved. For example, see the heel 501 of the tailored liner 415 thatis being produced. However, as a matter of process efficiency andavoiding time consuming steps involving subsequent component assembly,the entire charge may be simultaneously manufactured via threedimensional print techniques as depicted in FIG. 5.

Continuing with reference to FIG. 5, additive manufacturing, or threedimensional printing as referenced above, involves sequential layeringof materials to manufacture a product. In the case of a shaped charge asshown, a support 530 suspends a deposition tool 525 at an appropriateand ascendable height over the forming charge. A carrier 550 at a table575 therebelow may be moved via a conveyance 580 so as to allow thecharge to take shape layer by layer during the printing process.

In addition to rapidly providing a charge or complete gun system, suchthree dimensional printing may allow a degree of specialized precisionto components such as the liner 415, thereby optimizing performance. Forexample, in the case of the liner 415, tailoring the material gradientis rendered practical in addition to the morphology. In one embodiment,the liner 415 is of greater density, lesser porosity, or othercharacteristic at one end (e.g. at the skirt). Similarly, reactivematerials, wave shape features, or other performance features may beprecisely located at desired portions of the liner 415 due to theaccuracy of the print technology.

Similar benefit may also be provided to the case 150 and/or explosivepellet 175. For example, the case 150 may be of a controlled porositywith post explosive debris characteristics in mind The case 150 may evenbe of a multi-point initiation with tunnels at its base. By the sametoken, density, porosity and other characteristics of the pellet 175 maybe precisely provided layer by layer such that the explosive output andresultant jet performance is maximized This may even include providingselectively integrated non-explosive materials.

In one embodiment, the loading tube, gun and entire gun system may bethree dimensionally printed as described above. Thus, specializedmaterials such as fast corrosives or cavities may be layered into theseparts to reduce weight without substantial effect on performance.Indeed, the entire system may be constructed of materials such asreactives and fast corrosives that are configured to disintegrate or“disappear” upon detonation. Thus, little or no debris may be leftdownhole upon perforating.

Referring now to FIG. 6, a flow-chart is shown summarizing an embodimentof forming and utilizing shaped charges incorporating amorphousmaterials. As indicated above, a multi-material three dimensional printapplication may be used to form a shaped charge as noted at 610. Indeed,an entire gun system may also be manufactured in this manner (620). Thismay include printing of the gun followed by loading with componentassembled shaped charges as noted or the whole system, both gun andentire charges, may all be simultaneously printed as part of a singleprint application. Alternatively, as indicated at 630 and 640, componentassembled shaped charges may be separately printed or manufactured forloading into a separately provided gun.

As noted above, with completed shaped charges in hand, the gun may beloaded as indicated at 650 and lowered into the well for a perforatingapplication (see 660). As detailed hereinabove, benefits of utilizingamorphous materials, particularly those of the liner may be realized.Specifically, as indicated at 670, detonation of shaped charges may formperforations from a jet of characteristics enhanced by the utilizationof a liner of tailored amorphous materials. In fact, as indicated at680, debris-reducing reactions relative the gun, shaped chargecomponents or even perforation clean-out may follow the perforating as amanner of maximizing follow-on hydrocarbon recovery.

Embodiments described hereinabove include a shaped charge that may betailored of amorphous materials to substantially avoid the formation ofa liner material slug that may become wedged within a perforation tunnelduring the perforating. Thus, the effectiveness of the perforation forhydrocarbon uptake is not substantially hindered by such an occlusive orblocking type of material. By the same token, embodiments of the shapedcharge may also be tailored to ensure the formation of an effective jetupon firing of the shaped charge.
